As AI reshapes software, WorkOS is at the frontier of Human and Agent Authentication, Identity, and Access Control helping companies answer a new critical question: who are your agents, and what are they allowed to do? Our fast-growing customer base includes hundreds of modern software companies building the next generation of enterprise-ready products.

ABOUT THE SECURITY PLATFORM TEAM

The Infrastructure Security team provides and supports the primitives that enable engineering to securely build applications and meet compliance obligations, while abstracting away the underlying complexity for the best possible developer experience.

Our work centers on workload identity and authorization: how internal applications authenticate to each other and to the services they depend on, and how that access is granted and enforced. We're replacing static secrets with short-lived identity credentials, bringing identity-based authentication to the services engineers use every day, and unifying how authorization is managed across the company.

We're a platform engineering team with a security mission. We measure success by the security outcomes we enable and by how much engineers enjoy building on what we ship — the secure path should be the easiest path.

WHO WE'RE LOOKING FOR

- A platform builder. You love building infrastructure that other engineers rely on every day, and you sweat the developer experience details that make adoption effortless.

- Fluent in service-to-service auth. You know authentication and authorization deeply: JWTs, X.509 certificates, and when to reach for each.

- A systems thinker. You reason carefully about bootstrapping, circular dependencies, availability, and failure modes, especially for infrastructure that everything else depends on.

- A pragmatic migrator. You know that shipping the primitive is half the job. You can drive adoption across many teams, meet them where they are, and retire the legacy path.

- A strong partner to engineering. You build trust with engineers by understanding their priorities and making security frictionless.

- Excited about AI. You're embracing AI and automation to scale platform work and reduce toil.

- Curious and humble. You ask the basic questions, enjoy untangling complex systems, and bring others along with you.
